The Pena Adobe was constructed by Juan Felipe Pena in 1842 and is considered one of the oldest remaining structures in Solano County. This image shows the Adobe in the 1880’s with a wooden frame to help protect the adobe brick walls and to provide additional living space. This wooden frame was torn down in the late 1960’s when the Adobe was renovated for the first time.
The Pena Adobe was designated as a California State Historic landmark #534 in 1955. After a recent restoration by the City of Vacaville and Pena Adobe Historical Society, the Adobe and Museum is now open on the first Saturday of every month from 11 a.m. to 2 p.m.
